CHARLES SPAULDING, OF ST. JOllNSBURY, VERMONT.

IM PROVED CLOTH ES-WRINGER..

Specification forming part of Letters Patent No. 42,607, dated May 3, 1864.

To aZZ whom it may concern:

Be it known that I, CHARLES F. SPAULD ING,l a resident of St. J ohnsbury, in the county of Caledonia and State of Vermont, have invented an Improved Clothes VVringing and Squeezing Machine; and I do hereby declaro the same to be fully described in the following specication and represented in the accompanying drawings, of which- Figure 1 denotes a front elevation, Fig. 2 an end view,and Fig. 3 a vertical and longitudinal section, of it. A Fig. 4 lis an inner side view of one of slotted guards. Fig. 5 is an inner side view of one of the end portions of the frame.

The nature of my invention consists in the combination of eccentric guides or cams with the expressing-rollers and their supportingframe, the said guides being for the purpose or object as hereinafter set forth; also, in the combination of certain slotted guards with the rollers, the eccentric guides', and the frame; also, in the arrangementand combination of elastic springs with the eccentric guides and the rollers, the springs and guides by their cooperation serving to produce friction on the rollers while they may be in the process of expressinga liquid from clothing oran article The frame of the machine is composed of two end parts, A A', united by a cross-bar or rod, B. Two elastic rollers, C D, are disposed within the said frame in manner as repre sented in the drawings. The shaft a of the lower of these rollers is supported within and by boxes b I), each of which is arranged within one of the end portions, A A', of the frame, and is so applied thereto as to be capable of sliding vertically therein. Each of the said boxes -is supported on a vulcanized indiarubber spring, c, or ou a metallic cap, d, placed on the top of the spring.

The springs c rest on the bottoms of openings e, made within the end portions, A A', of the frame, each ofthe springs having the form as representedin Fig. 5. The upperpart, h, l

of each of the said openings constitutes not only a bearing but an eccentric guide for one i of the journals ff of the upper roller, C, the

said part h being curved eccentrically rela- I tively to the axis of the lower roller, and arrangedin manner as represented in the drawings. There are two elongated metallic caps or guards, G G, applied to the set' of rollers, each guard being arranged within the frame and made to cover the next two adjacent ends of the two rollers or lie against them or lap over the curved surfaces of the rollers, as shown in the drawings. Each of these guards, besides yhaving a circular hole, g, made through it for the reception of the shaft of the upper roller, G, has an elongated slot, k, for reception of the shaft of the lower roller,

D, such slot being necessary to enable the rollers to either approach toward or depart from one another as circumstances may rcquire.

A clamp, E, provided with a screw, t', and a nut, F, is applied to each of the two parts, A A', of the frame, and serves therewith to confine the machine to a wash-tub.

A crank being fixed on the shaft of the f lower roller, if such shaft be revolved in one direction by manual -power applied to the crank, not only will the two rollers be putin revolution, but, in consequence of the journals of the upper roller being rolled against the eccentric guides h h, the said roller will be moved forward on the lower roller and pressed toward it in such manner as to cause the axis ofthe upper roller to approach that of the lower one. p

On reversing the motion of the crank the upper roller will, be caused to fall back and its axis depart from that of the lower one. The object, therefore, of the eccentric guides h h is not only to aid in producing the neces- "sary pressure of the rollers on the clothes during the process of expressing liquid therefrom, but subsequently to relieve the rollers from the pressure against one another, the latter being acconiplishedby reversing the rotary motion of the crank. The slots It' k of the capguards G G enable the latter to move wnth the upper roller during its movements toward and away from the lower roller. These guards serve not only to protect the journals of the rollers from the liquid' expressed from thc clothes, but toprevent theclot-hes from being wound around the journals.

I do not claim the-invention of elastic rollers, nor do I claim, separately from the eccentric guides, the application of elastic springs to the bearings of pressurerollers, such application being common in Wrin gin g-machines.

I claim as my invention` 1. The combination of the eccentric guides h h With tlfe rollers C D .and their supportingframe, the whole being so arranged as to enable or cause the rollers to operate substantially as hereinbefore explained.

2. The combination of the slotted guards G Gr with the rollers C D, the eccentric guides h h, and the supporting-frame, the whole being arranged as specified.

3. The arrangement and combination of the elastic springs c-c, the eccentric guides h h, and the rollers C D.
